Leak to dry to treated, one company in Downham
Downham is dominated by the London County Council cottage estate built in the 1920s and 1930s, rows of pebbledash and render-fronted semis with solid brick walls and suspended timber ground floors, alongside pockets of ex-council flats and the prefab-style Excalibur bungalows nearby. This solid, older construction holds water differently to modern cavity walls, so leaks and floods need careful, targeted drying rather than a generic approach.

Drying challenges in Downham homes
Pebbledash and solid brick walls holding onto moisture
Many Downham cottages have solid brick walls finished in pebbledash render, with no cavity to break the path of water. When a leak or flood soaks the masonry, moisture becomes trapped behind the render and moves slowly through the brick. Surface plaster can feel dry within days while the wall core stays sodden for weeks, allowing mould and damp staining to reappear if drying is stopped too early.
Suspended timber floors over hidden voids
A large number of the estate's cottages were built with suspended timber ground floors sitting over a shallow void. Escaped water from a burst pipe or flooding easily runs beneath the floorboards, soaking joists and sleeper walls out of sight. Because the void is enclosed and hard to inspect, trapped moisture can sit against timber for a long time, raising the risk of swelling, rot and musty odours if it is not properly ventilated and dried.
Screeded extensions and converted flats on older plumbing
Kitchen and bathroom extensions added to Downham's terraces, along with converted flats carrying original pipework, often have solid screeded floors laid over the original subfloor. A leak from ageing pipes can saturate the screed and any covering above it, trapping water beneath tiles or laminate. Combined with limited underfloor ventilation typical of these later additions, this moisture is slow to escape and can encourage mould around skirting and cabinetry if not addressed.
What our customers say
Really impressed with the whole experience. The surveyor did a proper, thorough job and didn't rush anything, they got to the root cause of the damp and explained it all clearly. Detailed, professional and reassuring from start to finish. Couldn't recommend them more highly.
